Hi,
Is there a method to solve the system of absolute value linear equations:
|AX|=b
x belongs to {a,b}
This is a nonlinear method of solving a linear underlying equation
so is there a method of solving the minimum norm
min || |Ax|-b ||_{2} ,
x belongs to {a,b} ??
I have tried a multiple tweaks for iterative solvers but couldn't find a way
